Indonesia International Geothermal Convention

Mannvit has a booth and is presenting a technical paper at the 6th Indonesia International Geothermal Convention and Exhibition “IIGCE” 2018, held from 5-8 of September at the Jakarta Convention Center. The conference theme is “Empowering Geothermal for Indonesia’s Energy Sustainability”.

Mannvit is presenting at booth C-20 & C21 with CBN, an Indonesian EPC company, experienced in the Indonesian geothermal construction and project management business. We encourage all delegates to visit our booth to discuss your ideas and projects at this premier event in geothermal industry.

Mannvit, a world-leading geothermal consulting firm now has an office in Jakarta, and PT. Cipta Bangun Nusantara (CBN), an Indonesian geothermal contractor and engineering consultant, are co-operating in the Indonesian geothermal market. Together, Mannvit and CBN provide a full range of services to geothermal operators, developers and investors in Indonesia. The website of the conference is http://www.iigce.com/

The 6th IIGCE 2018 conference is a platform to share technical experience. This year, Dr. Ari Ingimundarson from Mannvit is presenting a paper named; “Analysis of risk mitigation strategies”. As the title suggests the paper is on geothermal risk mitigation, which usually involves reducing the risk of the developer in the exploratory drilling phase when the first wells are drilled. In this study, probability distributions regarding drilling success are used to simulate outcomes of exploration campaigns and using the outcomes, characteristics of distinct risk mitigation mechanisms are analyzed. Two drilling campaign scenarios are evaluated. Firstly, the influence of resource risk on a drilling campaign to reach 50 MW electrical output. The second scenario is a drilling campaign to reach 10 MW electrical output. This second scenario emulates an exploration drilling campaign in a green field. The main results of the article are the following. Contingent financial aid that is dependent on the outcome of the drilling provides higher impact per dollar spent and conversely, unconditional financial aid provides poor impact comparatively.  Contingent financial aid depending on the success of a group of wells provides much higher impact per dollar spent than considering the wells one by one. It is argued that average risk mitigation cost of providing a guarantee on MUSD/MW is not as high as expected.
